Purpose: This study provides a bibliometric analysis of global research on anterior segment optical coherence tomography (AS-OCT) in corneal diseases, mapping key research trajectories, collaborations, and emerging trends. Methods: A systematic search in the Web of Science Core Collection on January 1, 2025, retrieved 3634 records (1994–2024). After excluding non-English publications, non-ophthalmology studies, and non-corneal research, 2079 publications were analyzed using VOSviewer and CiteSpace for citation networks, coauthorship trends, and keyword co-occurrence. Results: AS-OCT research has grown significantly (Mann–Kendall τ = 0.929, P < .001). The United States led in publications (639 papers, 19,594 citations), followed by China (333 papers, 4502 citations). The University of California was the most productive institution. The first AS-OCT study, published in the Archives of Ophthalmology (1994) by Izatt JA et al, marked the field’s inception. The most cited article was Huang et al’s 1991 Science paper on optical coherence tomography. Recent trends highlight the integration of artificial intelligence, deep learning, and optical coherence elastography in AS-OCT applications. The top 3 contributing journals were Cornea, Journal of Refractive Surgery, and Journal of Cataract and Refractive Surgery. Coauthorship analysis identified Jodhbir S. Mehta and David Huang as central figures in AS-OCT research collaborations. Conclusion: AS-OCT research has expanded significantly, enhancing diagnostics, surgical planning, and disease monitoring. Artificial intelligence-driven analytics and optical coherence elastography are promising future directions. This bibliometric analysis guides advancing AS-OCT research and clinical applications.
